Zusammenfassung:Abstract: "We analyse three-dimesional models for computing transport of salinity, pollutants, suspended material (such as sediment or mud), etc. The main purpose of this paper is to present an overview of the various possibilities for the time discretization that can take advantage of the parallelization and vectorization facilities offered by CRAY type computers. Among the suitable time integration techniques, we have both explicit and implicit methods. In explicit methods, the parallelization is straightforward, but these methods are hampered by a severe time step restriction due to stability. This can be avoided by selecting an implicit method; however, such a choice necessitates the frequent solution of sets of tridiagonal equations
Since the solution of these equations requires the greater part of the total solution time, this part of the algorithm needs special attention in order to get good performance on parallel/vector architectures. Following a suggestion of Golub and Van Loan, we have experimented with several implementations on a CRAY YMP4, which will be reported.
